Wardner: I knew a Farmall ring and pinion or bull gears would not increase speed. I worded as I did, not knowing if those items might give extra speed if they came from a 300 or 350 Utility.
My reason on questioning this is I had Farmalls 300 governed at 1750 rpm and 560 governed at 2000 rpm, yet with 13.6x38 on 300 and 15.5x38 on 560 they maintained close to same speed on road in 5th travelling between farms. The 300 must have had faster ratio somewhere. I realize I'm talking larger chassis in 560, and that may make a difference. The other item that throws a kink in my thinking is Utilities always used 2000 rpm as governed speed.
Personally I think he's getting all his extra speed from those large tires, three sizes over factory standard tire. I only ever increased tires by one size and that makes a noticable speed increase in any tractor.
